(Di)cyclopentadiene(s) opt. contg. alkyl substituent(s) was thermally copolymd. with alpha, beta-unsatd. mononitrile and hydrogenated to give an amino resin which was treated with org. or inorg. acid, alkyl halide or halohydrin, and the water-sol. cationic amino resins were used for treating paper and fibre. In an example, dicyclopentadiene 452.4, acrylonitrile 72.6, and xylene 175 g. under N were autoclaved at 260 degrees for 6 hr. to give polymer (no av. mol.wt. 810) which was hydrogenated in the presence of Raney Ni and treated with acetic acid to give water-sol. cationic amino resin useful as paper internal size and water repellant for rock wool board |
